This herb is used for cold, stubborn phlegm with a full distended feeling in the chest and difficult expectoration. It is also used for wind conditions that cause convulsions, paralysis, spasms, stroke, dizziness, or epilepsy.

Chinese herbalists claim to have used it with success in some kinds of cancers and externally for suppurating sores and abscesses. When used externally, the unprepared root is indicated; otherwise it is used in its prepared form or with fresh ginger to counteract its toxic properties.

Dosage:
4-9 grams

Safety:

Arisaema rhizome should not be used during pregnancy or by those with yin-deficient cough with dry phlegm.
